The watermarking system proposed in this paper offers an expert system technique to help solve the ownership claim for accidental attacks on digital images. The proposed spatial domain watermarking system is based on fuzzy logic and was designed with the intent of embedding watermark features such that they are undetectable to the human visual system. To achieve this objective, the development ...

-With the increasing influence of digital network and communication, armour from perilous intrusion and corruption of information (e.g. image, video, speech etc) during transmission is a paramount issue. To protect the image and video from the unauthenticated access or tampering, watermarking is adopted as a solution. In this paper we have proposed a spatial domain Spread Spectrum (SS) watermar...

The information about 3D atomic coordinates of chemical structures is valuable knowledge in many respect. For large sets of different structures, the computation or measurement of these coordinates is an expensive process. Therefore, the originator of such a data set is interested in enforcing his intellectual property right. In this paper, a method for copyright protection of chemical structur...

Due to the extensive use of digital media applications, multimedia security and copyright protection has gained tremendous importance. Digital Watermarking is a technology used for the copyright protection of digital applications. In this project, a comprehensive approach for watermarking digital image is introduced. We propose a hybrid digital watermarking scheme based on Discrete Wavelet Tran...

Error-resilient variable length codes (VLCs) have been proposed to counter bit errors over error-prone channels. In this work we establish a linkage between channel coding and watermarking by observing that watermark bits are, in effect, intentional bit errors. Using a recently introduced resynchronizing VLC, we have developed a compressed-domain watermarking algorithm where the inherent errorr...

Digital watermarking is a process of embedding unobtrusive marks or labels into digital content. These embedded marks are typically imperceptible (invisible) that can later be detected or extracted. This paper describes watermarking process and attacks on watermarks. Also a focus is made on various techniques of implementing watermarks. In general, any watermarking scheme consists of three part...

In this article we propose a new fragile watermarking algorithm that provides the means to verify the integrity of JPEG images. We begin by presenting the cryptanalysis of CWSA (Chaotic Watermarking Scheme for the Authentication of JPEG Images), an existing fragile watermarking algorithm. We analyse its weaknesses and we propose a new version that is resistant to those attacks, faster and less ...

In recent literature many strategies for attacking and subverting a watermark have been presented. Such attacks suggest t ha t the ability t o embed non-erasable watermarks does not necessarily imply tha t the watermarking scheme can be used t o establish ownership. The main aim of this paper is t o formulate necessary and sufzcient requirements for a watermarking scheme t o be able t o resolve...

Watermarking is a process of embedding one image into another image, used to protect the from copyright infringement; main aim this watermarking provide ownership assertion- only rightful owner can extract watermark prove ownership. Day-to-day attacks on digital content (like images) are increasing, but still same traditional for protection. In static watermarks at source which may lead comprom...

Digital Watermarking: ~ From Concepts to \ ’ . Real-Time Video Amdications II--r digital watermarking field was born around the same time that the World Wide Web started its phenomenal growth. In recent years, digital watermarking has become increasingly applied to hide information in digital multimedia data, thus enlisting the water-marking technology in the difficult fight against intellectua...
